Grip tape

ABSTRACT

A grip tape includes a base layer covered by a first adhesive layer. The first adhesive layer is partially covered by a second adhesive layer that is adjacent to one lateral edge of the first adhesive layer. The first adhesive layer, after being attached to the grip tape, is adhesive and used to wrap a grip portion of a baseball bat or the like. By applying pressing, the first adhesive layer is tightly affixed to a peripheral wall of the base layer. The second adhesive layer includes hot glue and is wound together with the grip tape around the baseball bat in a predetermined angle so that the second adhesive layer overlaps a felt sheet or other materials in the base layer. At last, after a process of thermocompression bond or thermal reaction, the both can be tightly bound with each other.

BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to grip tapes, and more particularly to agrip tape that wraps the grip portion of an external tool, such as abat, racquet, a club or the like.

2. Description of Related Art

Referring to FIG. 1, a grip tape 10 is used to cover or wrap a gripportion of a baseball bat 1. There are many types of adhesive usable tomake the grip tape 10. Conventionally, in a process for producing thegrip tape 10, an adhesive sheet or a gluing member first has its stickyside or surface attached to the side of the grip tape 10 that will beused for adhesion or affixion. Then the grip tape 10 is wound to havesome overlapped portions. Afterward, an external force is applied to theperiphery of the wound grip tape 10 so as to make the overlappedportions of the grip tape 10 adhered to or bound with each other throughthe adhesive sheet or a gluing member.

However, in the event that the sticky side or surface of the adhesivesheet or a gluing member is poorly affixed to the grip tape 10, or inthe event that the grip tape 10 is poorly mounted or wound, or in theevent that a user grips the baseball bat 1 with the grip tape 10improperly and damages the grip tape 10, the grip tape 10 has to beredone or rewound around the grip portion. The redoing or rewinding ofthe grip tape 10 may cause the adhesive combination between the baseballbat 1 and the grip tape 10 significantly degraded. This makes theprocess and operation inconvenient.
